Installation of Curt Brake Controller Adapter

To install your Curt electric brake controller, you need to connect the wiring of the controller to your vehicle. Certain auto manufacturers offer pre-wired options, typically known as tow packages, wherein wiring is run for you from the dash to the trailer connector on the back of your vehicle. When this is done, a port is installed at your dash so that you can easily plug in a brake controller.


This adapter plugs into the port on your vehicle's built-in brake control wiring harness. For most applications, this harness is located behind the dash.


No hardwiring is required to install this adapter. After you plug it into the factory port, you simply plug the other end of the adapter directly into your electric trailer brake controller. Because there are no wires to connect, installation is not permanent. You can unplug and remove your brake controller at any time to transfer it to another vehicle or securely stow it away.

Kate M. my salesperson, had a most professional interaction with me being certain of my and my vehicle's needs. In addition, she walked me through the complete installation process. This I completed, wiring the 7-way and the Curt Discovery Controller making no errors along the way. On the first test, every terminal on the 7-way tested as it should. When we came home with the RV from the dealer, all the lights and the brakes worked flawlessly. Many thanks!!

Adapted Curt brake controller for my 2014 Ford F150 STX without any problems. Just find your Ford brake control connector behind the coin slot on the left side of the dash and plug it in.

2009 Ford F-150

The Curt wiring adapter for my 2009 Ford F-150 plugged into the controller and the truck connector under the dashboard exactly as it should have. It works great.



by:

Installing and using the Curt trailer brake controller was simple and worked perfectly. I Can say the same about the customer service at etrailer. And will certainly be using them both



by:
2010 Ford F-150

The cable assembly made installation quick and easy, all I had to do was locate the Ford supplied connector in my F150. The cable assembly supplied by Curt plugs into the Ford provided connector. Plug the opposite end of the Curt supplied cable into the controller and the electrical installation is complete. Note: the Ford supplied connector has a protective cover on it, you have to remove this cover before this Curt connector will plug in.

I am very happy with all of my purchases from etrailer. The products are still working fine after a year and your company is very good to work with. Any future needs I have will be purchased at etrailer.

Simple plug and play, installed in less than 30 minutes in my f150. A++++



by:
2013 Ford F-150

Etrailer provided outstanding information regarding the technical details of the product along with easy to understand installation instructions. The brake controller provided a cost effective solution for my basic requirements. The installation was a "snap", the only time consuming task was determining the optimal location/position install the brake controller. Item was installed in a 2013 Ford F150 and I use it on a dual axle trailer for hauling a compact Kubota tractor.



by:
2012 Ford F-150

Excellent - no hesitation in making that evaluation

I bought a brake controller, interface cable for the F150, and the 7 pin plug that goes on the back bumper. All items are great quality. Parts arrived as expected with shipping as paid for. I am installing the equipment, but don't have any issues. There were no installation instructions, however these are available on line line detail. I do not expect any operational probems but am a few days from making that test.



by:
2009 Ford F-150

Researched, purchased and installed a hitch and brake controller for my 2009 F-150. It was so much easier using etrailer. I have recommended them to several friends for their towing needs.



by:
2016 Ford F-150

This pigtail that Dan T. with e-trailer help me get order an shipped worked perfectly. It was a custom fit for 2016 F-150 w/ no tow pkg and a Curt 51120 brake controller. This will almost complete my conversion of my truck that had no tow pkg. In the end it will help my daughter tow her Shooting S barrel horse safely to the shows. Thank you Dan T.

2012 Saturn Relay

Made install easy. I ran my own 12 ga wire to 7 pin connector for trailer brakes. I couldnt find the fuse and or relay needed for my 2011 F150 to complete factory circuit. I NEEDED the trailer the next day with a 3,000 lb tractor on it. Worked well.

  • Recommended Curt Brake Controller Adapters for a 2020 Ford F-150
    If your 2020 Ford F-150 came with a 4-way or 7-way from the factory you can use the Curt Custom Wiring Adapter item # C51436 to install the Venturer Brake Controller item # C51110. If your truck didn't come with a 7-way or 4-way connector then you don't have the towing package and will need to use the Universal Wiring Adapter for Curt Trailer Brake Controllers item # C51515.

  • Brake Controller Wiring Adapter for 2014 Ford F-150
    The adapter you need to install an electric brake controller in your 2014 Ford F-150 depend on which controller you have. If you don't already have a controller I recommend the Prodigy P3, part # 90195, because it's the easiest to use and install. For the P3, or any other Tekonsha controller use part # 22292 for the adapter. A few other popular brands: For Hayes controllers use part # HA81794-HBC For Hopkins controllers use part # HM47845 For Curt controllers use part # C51436 If you...

  • Installation of Curt Venturer Brake Controller # C74VV in 2011 Ford F-150
    Your 2011 Ford F-150 has a quick-connect port under the dash to allow for convenient plug-in installation of a trailer brake controller. The harness part you referenced, part # C51436, provides this connection instead of forcing you to hard-wire the unit. Your harness may be pinned out incorrectly for your 2011 F-150. Please refer to the linked article which explains the correct pin assignments for the harness you have. It may just be necessary for you to relocate the ground and brake...

  • Does Dealer Need to Turn on Aftermarket Brake Controller in a 2015 Ford F-150?
    There will be no need for you to go to take your 2015 Ford F-150 to the dealer to have them turn on an aftermarket brake controller. The brake controller I recommend that you need only an adapter for is the Curt Discovery # C84VV. Since you already have the factory tow package, just use the Plug-In Wiring Adapter # C51436. Plug one side into the brake controller and the other side into the wiring on your F-150 and you are done.

  • Can 2017 Ford F-150 With 7-Way Have Trailer Brake Controller Installed
    So, I'm going to go ahead and rip the Band-Aid off right here - your dealership is very wrong and your 2017 Ford F-150 can absolutely have a trailer brake controller installed. They are wrong about not being able to add one and wrong about there not being a module/wiring connection. It is up and under the dash on the right side; I have added a photo from an install we did on a '17 F-150 showing the port. That said, I don't recommend using the Curt Echo # C51180. The reason why is 2015-2017...

  • Curt Brake Controller Adapter For 2019 Ford Expedition
    I am happy to help you install the Curt Triflex part # C24VV in your 2019 Ford Expedition with a factory 7-way. I recommend to use Curt Custom Wiring Adapter for Trailer Brake Controllers part # C51436 to install the brake controller. It will plug into a built-in port under the dash of the Ford and the other end plugs into the brake controller to power the brake output circuit on the 7-way to tow a trailer with brakes.

  • Recommended Out of the Way Brake Controller for 2009 Ford F-150 With Factory 7-Way
    The Curt TriFlex Trailer Brake Controller # C24VV with Wiring Adapter # C51436 is a very good option for your 2009 Ford F-150, though to mount it you will need to use the included mounting bracket and screw it in under the dash. If you (understandably) don't want a brake controller unit in the cab of your F-150, you do have a great option I recommend checking out, the Curt Echo Mobile Trailer Brake Controller # C51180. The Echo is the best option because it will simply plug into the 7-way...

  • Where Does Brake Controller Plug in on 2016 Lincoln Navigator
    Yes, that's correct. To install the Curt Spectrum, part # C51170, or any brake controller you can use a custom harness to just plug it in. The harness is part # C51436. We don't have a video that shows the location of the connector but it's too the right of the steering wheel.

  • Hardwiring in a 7-Way Trailer Connector and Brake Controller on a 2018 Ford F-150 w/Factory 4-Way
    I did some checking and right now, in order to add a 7-Way trailer connector to your 2018 Ford F-150, you will need to use our hardwire kit # ETBC7. The factory brake controller wiring harness might be in place but if it is for sure and if that means you can install the Ford brake controller I cannot answer. I am sure you can though because I know in other Ford F-150s you can. Or you could install an aftermarket brake controller using wiring harness # 22292 and a Tekonsha brake controller....

  • Does Computer Need To Be Flashed When Installing Brake Controller On 2021 F150?
    The OEM brake controller requires your 2021 Ford F-150 to be flashed by the dealer. However, an aftermarket brake controller like the Curt Assure Trailer Brake Controller - # C49UR does not require the dealer to flash your truck's computer. You will need Plug-In Wiring Adapter # C51436 to connect the brake controller to the factory plug-in on your truck. Keep in mind, not all 2021 models have the necessary 12V going to the plug-in, so you may end up needing to install Power Wire Kit for...

  • Brake Controller Recommendation and Install for a 2014 Ford F-150
    If you have a factory 7-way connector at the rear of your 2014 Ford F-150 I would recommend the Curt Brake Controller part # C24VV and the install harness part # C51436. These two parts will make installation very easy as the harness plugs into the controller and then the other end plugs into the port under your dash. If you have a factory 4-way connection at the rear of your vehicle you will also need the part # 37185 to complete the install. Check out the FAQ article to the right for...

  • Where Does Wiring Harness for Curt Venturer Connect to in Cab of 2016 Ford F-150
    The Curt Venturer Brake Controller # C74VV installs with the wiring harness # C51436 behind a panel in your 2016 Ford F-150's dash counsel. The panel you will need to remove in just to the right on the steering wheel. See the video I've attached and skip ahead to about the 2:30 mark to see the panel. From their the video will show you the rest of the install.

  • Should Curt Spectrum Brake Controller Show Lights on Display When Connected to Truck
    With a trailer disconnected the Curt Spectrum part # C51170 that you referenced should have the outer two lights flashing blue at idle or solid blue when the brakes are on. Since you used the correct install harness for this controller in your 2010 Ford F-150, part # C51436 you most likely have a blown fuse under the hood of the truck for the brake controller circuit. That would be only thing that would kill the circuits that power the controller.

  • Parts Needed to Install Curt Venturer Brake Controller in 2018 Ford F-150 with 7-Way
    To install the Curt Venturer brake controller part # C74VV all you need is the install harness part # C51436 that you referenced. This plugs into the port on your controller under the dash and then into the connector of the Venturer. You would not need to flash the computer of the truck either.

  • Is There A Plug-In Wire Harness Adapter For An Aftermarket Brake Controller In A 2022 Ford F-150
    From what I can find 2021+ Ford F-150 models are either coming without the plug or come with equipment that has to be activated by a Ford dealer, making it harder on consumers to install aftermarket brake controllers. Because of this you'll likely have to use a universal splice-in wire harness like part # C51515 to install your Curt Spectrum Trailer Brake Controller # C51170. Curt lists the Curt Custom Wiring Adapter for Trailer Brake Controllers # C51436 as a fit, but I would open up...

  • Location For Brake Controller Adapter # C51436 To Plug Into On 2010 Ford F-150
    On your Ford 2010 F-150, the harness location should be located under the dash, above the brake pedal and taped to another harness. I have attached a photo that shows the typical location for the harness location on your truck. If you have the shifter in the center console of your F-150 it will be located under the center console. I have attached the installation instructions for the Curt Custom Wiring Adapter, part # C51436. The instructions show the typical installation locations for...

  • Can Same Harness be Used when Switching From Curt Time Delayed to Curt Proportional Controller
    To replace the existing trailer brake controller on your 2009 Ford F-150 with a Curt proportional unit, such as the Curt TriFlex # C24VV, you can indeed use the same Plug-In Adapter part # C51436 that you used before. You will just need to unplug your old unit and plug the adapter end into the new Curt controller. The TriFlex is a really nice, proportional controller that will activate the trailer brakes at the same time and with the same intensity that you apply to them in your F-150....

  • Is The Curt TriFlex Trailer Brake Controller Compatible With a 2010 Ford F-150?
    Yes, the Curt TriFlex Trailer Brake Controller # C24VV can be used on your 2010 Ford F-150. As you have the factory tow package you only need the Curt Custom Wiring Adapter # C51436 to connect to the factory connection under the dash.

  • Trailer Brake Controller Recommendation for 2022 Ford F-150
    Since you have more than one trailer I would recommend the Curt Echo Under Dash Brake Controller part # C27JR as it has ability to save different trailer profiles so you can more easily go between trailers without having to completely set up the brake controller. This an under dash controller that once installed just needs to sync to your smartphone and is ready to tow with. The correct install harness for this and your 2022 Ford F-150 would be the # C51436 and you'd be set.

    To install the Curt TriFlex NEXT Trailer Brake Controller # C24VV to your 2018 Ford F-150 I recommend also picking up the Custom Wiring Adapter # C51436 so the installation is a plug and play setup. You'll be able to find the OEM connector on your Ford behind the center console controls (see attached instructions). If your F-150 came from the factory with a 7-Way connector at the back then you're good to go, otherwise if it came with the 4-Way then you also need the Universal Installation...

  • 2019 F150 Trailer Brake Controller Wire Size
    I'm not entirely sure a relay is used on that circuit, but it would provide a good explanation for the smaller wire gauge used on the factory pigtail. There's really no need to hardwire the controller. If the small wire gauge concerns you, there's an aftermarket one available, part # 22292. The black power wire and the blue brake output wire are both 12 gauge and the red stop lamp switch wire and the ground wire are both 16 gauge. This harness is designed for use with Tekonsha brake controllers,...
